SPECIFICATION forming part of Letters Patent No. 400,106, dated March 26, 1889.

Application filed December 13, 1888. Serial No. 298,477. (No model.)

To all whom it may concern.-

Be it known that I, DE \VITT A. MOON, of Orlando, in the county of Orange and State of Florida, have invented certain new and use ful Improvements in Colters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in colters; and it consists in, first, the combination of the shoe, which is recessed at its rear end, so as to extend uponboth sides of the colter, with the revolving colter and suitable boxes placed upon the rear ends of the shoe; second, the combination of the revolving colter, recessed collars applied to opposite sides thereof, the journal, and the boxes provided with scrapers for preventing the collars from becoming clogged with dirt, as will be more fully described hereinafter.

The objects of my invention are to recess the rear end of the shoe, so as to have it extend upon both sides of the colter, and thus support the colter-shaft at both ends alike; to provide the boxes with scrapers for keeping the recessed collars clean; to so arrange the boxes that they will have an independent movement of their own, and thus adapt themselves to the movement of the shaft, and to so construct the shoe that it will ride over obstructions and hold them down, so as to be cut by the colter.

Figure 1 is aside elevation of a colter which embodies my invention. Fig. 2 is a plan view, partly in section, of the same. Fig. 3 is a vertical section through the rear end of the shoe and the boxes. Fig. 4 is a side elevation of one of the boxes alone.

A represents the shoe, which is attached to the beam by the rod or hanger B, and which shoe is provided with the strengtheningflange O, which has a vertical opening formed through it to receive the lower end of the rod or hanger. This flange 0 extends backward along the top of each one of the ends of the shoe and as far as the covers D to the boxes E will allow. The rear end of the shoe is bifurcated, as here shown, so as to form a support upon each side of the colter F for one of the boxes E, and thus support the shaft G of the colter at both ends alike. \Vhere the shaft is supported at one end only, it soon wears uneven and allows the colter F to have an irregular wabbling movement.

Extending horizontally across the top of each one of the ends of the shoe are the flanges H, which serve to help to hold the boxes E in position, and thus prevent them from having any lateral movement. The central portion of the rear ends of the shoe, where the boxes E rest upon them, are made crowning, and the inner sides of the covers D for the boxes are also made crowning, so that the own, and thus accommodate themselves to the movement of the shaft G, so as to prevent binding. The outer ends of these boxes E are flared, as shown, and these flared ends fit in the recessed sides of the collars I, between which the colter F is held. One of these collars I has a slight shoulder or offset made in its side, so as to receive the corresponding shoulder, J, upon the shaft G. This shaft G is also provided with a screw-thread, upon which one of the collars screws, so as to clamp the colter F tightly between them, one of the collars being prevented from having lateral movement upon the shaft'by its offset and the collar J. This shaft G upon the outer side of each one of the collars I and inside of the flaring end of each of the boxes E is grooved or reduced in size, so that dirt cannot so readily work itself into the bearings, and any sand that may get into the shaft will be caught in the groove and carried over where it will drop out on the inside of the flared portion of the boxing, and because of this flared portion the sand will be worked out between the ends of boxes and inside of collar.

To prevent the dirt from working into the boxes E, each one of the covers D is provided with a projecting flange, L, at its inner end, and this flange extends a suitable distance over the recessed ends of the collars I, between which the colter is clamped. Upon the inner side of each one of the ends of the shoe is also formed a corresponding flange, N, which forms a continuation of this flange L, and prevents any dirt from being caught as the colter moves forward and being forced into the boxes. As some of the dirt will inboxes E can have a slight movement of their evitably work inside of the flanges L and N and into the recess made in the collar 1, each one of the boxes is provided with a scraper, O, at its inner end, and these scrapers, fitting inside of the collars I, scrape out all of the dirt which may work into the collars as they revolve. As no dirt is allowed to accumulate inside of the recessed portions of the collars, the dirt cannot work inside of the recessed ends of the boxes E, and thus there is little danger of the shaft and boxes becoming clogged.

Through the top of each one of the covers D and through the upper portion of each of the boxes E is formed an oil-hole, as shown, so as to allow the oil to pass directly in upon the shaft G.

As will be seen from the construction here shown, the rear end of the shoe is pronged, so as to extend upon each side of the colter F, which is sharpened upon one side only, so as to enable a sharper edge to be formed. The divided ends of the shoe form two separate bearings for boxes for the colter-shaft, and it is thus made to always revolve evenly and true at the same time that the vines are held down, so that the colter can cut them more easily.

Having thus described my invention, I claim- 1. A shoe divided at its rear end, in combination with the colter F and boxes for the colter-shaft placed upon the two ends of the shoe, which extend upon both sides of the colter, substantially as shown.

2. The combination of the revolving colter, the recessed collars between which the colter is held, the shaft G, which extends beyond each of the collars, and the two boxes E, supported upon the two ends of the shoe, substantially as described.

The combination of the colter, the two recessed collars between which the colter is clamped, the colter-shaft, the shoe provided with recessed or divided ends, so as to project upon both sides of the colter, the boxes E, and the covers D, provided with the flanges L, and the flanges N upon the shoe, substantially as described.

a. The combination of the colter-shatt, the boxes E, provided with the scrapers O, and recessed collars, between which the colter is clamped, substantially as specified.

5. The combination of the shoe provided with the recessed end, so as to extend upon both sides of the colter, and provided with the flanges II, the boxes E, placed between the flanges, and the covers D, which are placed over the boxes, so as to hold them in position with the colter-shaft G, the recessed collars I, and the scrapers 0 upon the inner ends of the boxes, substantially as shown and described.

6. The combination of the shoe having a pronged end, the boxes which are applied to these pronged ends, and the covers which are placed over the boxes, the ends of the shoe and the inner sides of the covers being rounded, so that the boxes can have a rocking movement, substantially as set forth.

I11 testimony whereof I aflix my signature in presence of two witnesses.
